ReviewOral lactoferrin for the prevention of sepsis and necrotizing enterocolitis in preterm infants.
Lactoferrin, a normal component of human colostrum, milk, tears and saliva can enhance host defence and may be effective in the prevention of sepsis and necrotizing enterocolitis (NEC) in preterm neonates. ⋯ Oral lactoferrin prophylaxis reduces the incidence of late-onset sepsis in infants weighing less than 1500 g and most effective in infants weighing less than 1000 g. There is no evidence of efficacy of oral lactoferrin (given alone) in the prevention of NEC in preterm neonates.Well designed, randomized trials should address dosing, duration, type of lactoferrin (bovine or human) prophylaxis in prevention of sepsis and NEC. The effect of exclusive maternal milk feeding should be clarified.

ReviewThe psychological effects of the physical healthcare environment on healthcare personnel.
The physical healthcare environment is capable of affecting patients. This concept of 'healing environments' refers to the psychological impact of environmental stimuli through sensory perceptions. It excludes more physiological effects such as those produced by ergonomic (i.e. fall prevention) or facilitative (i.e. hygiene-related) variables. The importance of an atmosphere in the healthcare environment that promotes the health and well-being of patients is evident, but this environment should not negatively affect healthcare personnel. The physical healthcare environment is part of the personnel's 'workscape'. This can make the environment an important determinant of subjective work-related outcomes like job satisfaction and well-being, as well as of objective outcomes like absenteeism or quality of care. In order to effectively build or renovate healthcare facilities, it is necessary to pay attention to the needs of both patients and healthcare personnel. ⋯ One study was included in this review. This review therefore indicates that, at present, there is insufficient evidence to support or refute the impact of the physical healthcare environment on work-related outcomes of healthcare staff. Methodological shortcomings, particularly confounding with other variables and the lack of adequate control conditions, partially account for this lack of evidence. Given these methodological issues, the field is in need of well-conducted controlled trials.

ReviewLamivudine with or without adefovir dipivoxil for postoperative hepatocellular carcinoma.
Hepatocellular carcinoma (HCC) is a significant cause of death, especially in Asia and sub-Saharan Africa. Removal of the cancer through surgery or other techniques is considered the first-line therapy in early HCC, but relapse of HCC is the main postoperative problem. The main risk factor for HCC is hepatitis B virus (HBV) infection. Lamivudine and adefovir dipivoxil are effective and tolerable for chronic hepatitis B by suppressing the viral load and to reduce fibrosis in the liver. ⋯ No evidence from randomised trials on the beneficial or harmful effects of lamivudine with or without adefovir dipivoxil for postoperative HCC was found. Randomised clinical trials with large number of participants and long follow-up period should be carried out to direct clinical practice.
